arch/ia64/Makefile tweak

If the gcc in your PATH is version 2.X and you are not using cross tools (the CROSS_COMPILE make macro is null) make CC=<path to a 3.X gcc> fails due to the lack of --param max-inline-insns 00 on the compile lines.

This happens because GCC_VERSION in arch/ia64/Makefile is determined using $(CROSS_COMPILE)$(HOSTCC) which expands "gcc" picking up gcc 2.X. With GCC_VERSION defined as 2 the additional CFLAGS options within the ifneq ($(GCC_VERSION),2) are not being added.

You can work around the problem by also setting HOSTCC on the make command line
e.g. make CC=<path to a 3.X gcc> HOSTCC=<path to a 3.X gcc>
but I believe the correct solution is to use $(CC) instead of $(CROSS_COMPILE)$(HOSTCC) to determine GCC_VERSION.

Applied, thanks.

In the future, please send properly formatted patches, so that they can be applied with "patch -p1". This avoids creating extra work when applying the patch in the bitkeepr tree.

Thanks,
